[Bug c/19994] New: warn on parameter name mismatch

[cyeoh at samba dot org]

Would like to be able to get a warning when parameter names don't match
the prototype. eg. 

void foo(int x, int y);

then doing

void foo(int y, int x)
{
}

should generate a warning.

prototypes in header files can get out of sync with the function definitions (or
parameters are simply get swapped around accidentally) - even with experienced
programmers. 

Users of that interface then get unexpect behaviour. I still think an optional
warning would be useful - and it wouldn't be on by default.

I think it would be fairly unusual that you would want the prototype parameter
names to not match the definition. It wouldn't have to warn if the parameter
names in the prototype were deliberately omitted.
